Too Many Mistakes

The police simply made too many mistakes.  I will take into consideration the time period and the limited technology but still beyond that, the police really messed up the case.  The newspapers/media should not have found out intimate details of the investigation.  The police force should have known the area they were patrolling much better.  Washing away/erasing vital evidence to the case is inexcusable.  With the contradictory police reports, and lack of communication, the Metropolitan Police force might as well be called FEMA.
